Sea rabbits are not rabbits. The two pairs of antennae on the head of the sea rabbit protrude like rabbit ears, and the body is smooth or has many protrusions. The antenna has a clear division of labor, and the front pair is slightly shorter, specializing in touch control; The back couple is a little longer.
When the sea rabbit crawls on the bottom of the sea, a pair of antennae at the back are separated into a figure of eight and extend obliquely forward to smell the surrounding smell. When resting, the tentacles immediately come together and go straight up, just like the two long ears of a rabbit. When not moving, it looks like a small white rabbit squatting on the ground, with a pair of big ears, so it was first called a sea rabbit by the Romans.
Extended data:
When a creature is attacked by a predator, the method of transferring the attack can be to induce the predator to attack those sacrificial and exciting parts.
For example, sea slugs have bright red nipples. If it is disturbed, these nipples will swing around and the fish will bite them. Nipples can regenerate after being bitten off. But because the mastoid contains stinging cells and gland secretions, predators will discard them and will not attack them again.
There are more than 3,000 species of sea rabbits, which are distributed all over the world, including tropical and Antarctic waters. Although sea rabbits are distributed along the coast of China, especially in the southeast coast, and live in tropical waters, their colorful appearance is very ornamental.
